The romance rumors are swirling once more since Sandra Bullock and Ryan Reynolds were spied vacationing together with Sandra's baby boy in tow.

The Proposal costars were spotted hiking in Wyoming's Grand Teton National Park -- and Reynolds carried Bullock's baby boy Louis on his back!

Was Reynolds playing Daddy or just Uncle Ryan? While fans would love to see these two longtime friends hook up for real, sources say that there is no smoochy-smoochy happening -- yet.

"They're very close and talk together a lot," a source close to Reynolds told Us Weekly. "It would make sense for them to pair up romantically, but for now, they're just friends."

Bullock denied a romance with Reynolds last January.

Darn it! These two would make a great couple. Ryan Reynolds is the sexiest man alive, they both seem so nice and down to earth, and they could help each other get over their failed marriages. Reynolds split from Scarlett Johansson in 2010, and Sandy dumped her no-good cheating husband Jesse James earlier that year.
